How often I perceive in the correspondence of the 'spiritual' to this section a contempt for the material.

The adjective "spiritual" applied to religions is a fraud, clear and simple. Every religion aims at manifest -- and thus material -- results. Every religion is based on tangible and precise -- and thus material -- practices. Every religion relies on guarantees that are historic and thus material -- or revealed -- and thus materialized. Every religion directs itself towards individual - and thus egotistical and thus material -- hopes. That every religion also requires a show of contempt for the material merely adds to the hypocrisy of the whole thing.
